Abstract
Disclosed are an image encoding and decoding method, image processing device, and computer storage medium. the image coding method includes: when copying coding is performed on a current coding block by using one of the at least two different palette and pixel string copying coding manners, generating a new palette color according to pixels of the current coding block; generating a palette for the current coding block according to the new palette color and a palette color candidate set shared by the at least two different palette and pixel string copying coding manners; and performing palette and pixel string copying coding by using the palette for the current coding block, and generating a video bitstream comprising a copying manner and a copying parameter.
